|Father||Gary Harrison Sr.|
|Voiced by||Kyle McCulloch|
|First Appearance||All About Mormons|
A new student from Utah who is Mormon. He's a state champion in wrestling and tennis, an honor student, and has been on two national commercials for toothpaste. And he's also ridiculously nice. Despite all this, the Boys show him no love, and vow to kick his ass.
Gary's personality appears to be shaped largely by his family and religion, Mormonism. He is friendly, outgoing, and optimistic. When he is teased and bullied by other students at school, he doesn't appear to be bothered by it. For example, in All About Mormons, Eric Cartman introduces himself to Gary as "Ura Fag." Rather than acting upset or embarrassed, Gary laughs. Later, when Stan threatens to “kick [his] ass,” Gary promises not to fight back and even hopes that they can be friends someday.
Although he's friendly and forgiving, Gary is not a pushover. When Stan refuses to be Gary's friend because of his religion, Gary responds with a very thoughtful speech about how proud he is to be Mormon and what it has done for him. The speech ends with: "All I ever did was try to be your friend, Stan. But you were so high and mighty that you couldn't just look past my religion and be my friend back. You've got a lot of growing up to do, buddy. Suck my balls."
"Stan, I remember you said last night that you'd lost your wallet, so I made you a new one. I carved a picture of John Elway into the leather on the front."
"All I ever did was try to be your friend, Stan, but you're so high and mighty you couldn't look past my religion and just be my friend back. You've got a lot of growing up to do, buddy. Suck my balls."
